ARTICULATIONS
Joints in the Human BodySlide2
What are articulations?
Articulations are jointsPlaces where two or more bones meetSlide3
There are 3 major categories:
Fibrous joints, aka synarthrotic jointsCartilaginous joints, aka amphiarthroticSynovial joints, aka
diarthrotic
jointsSlide4
Fibrous joints - synarthrotic
Two or more bones joined by fibrous connective tissueCan have very limited but usually no motionSlide5
Three types of fibrous joints
SUTURES: located between bones of the skull. They are immovable.
FONTANELS
are areas of
unossified
bone in children under two years old.Slide6
syndesmoses
In a
syndesmosis
joint, bones are farther apart than in sutures and they are also connected by
ligaments.Slide7
gomphoses
A
Gomphosis
is a “peg” held in a socket by fibrous tissue. Teeth held in the maxilla and mandible by periodontal ligaments are examples..Slide8
Review: The three fibrous joints are????
SuturesSyndesmosesgomphosesSlide9
The cartilaginous joints
AMPHIARTHROTIC JOINTSSlide10
Cartilaginous joints:
Two or more bones connected by hyaline or fibrocartilage.This type of joint provides limited motionSlide11
Two types of cartilaginous joints:
Synchondroses:Bones connected by hyaline cartilageLittle or no motionEx: epiphyseal plates
Symphyses
:
Bones connected by
fibrocartilage
Provide slight motion
Ex: vertebrae and pubic bonesSlide12
